A plant or refinery may include equipment such as reactors, heaters, heat exchangers, regenerators, separators, or the like. Types of heat exchangers include shell and tube, plate, plate and shell, plate fin, air cooled, wetted-surface air cooled, or the like. Operating methods may impact deterioration in equipment condition, prolong equipment life, extend production operating time, or provide other benefits. Mechanical or digital sensors may be used for monitoring equipment, and sensor data may be programmatically analyzed to identify developing problems. For example, sensors may be used in conjunction with one or more system components to detect and correct maldistribution, cross-leakage, strain, pre-leakage, thermal stresses, fouling, vibration, problems in liquid lifting, conditions that can affect air-cooled exchangers, conditions that can affect a wetted-surface air-cooled heat exchanger, or the like. An operating condition or mode may be adjusted to prolong equipment life or avoid equipment failure.

A fluid flow-path device facilitates a maintenance operation to remove a foreign substance adhered to a member, to prevent passage of the foreign material. The fluid flow-path device has a distribution header including a partition member and a header body in a flow-path formation body. The partition member partitions a distribution space of the distribution header into an upstream-side space that communicates with a supply opening in the header body, and a downstream-side space that communicates with a plurality of flow paths in the flow-path formation body. The partition member includes a region that prevents a foreign substance in a fluid from flowing from the upstream-side space to the downstream-side space, while allowing the fluid to flow. The header body has an opening that allows a washing fluid to flow into the downstream-side space, and an opening that allows the washing fluid to be discharged from the upstream-side space.

A microchannel heat exchanger (MCHX) includes an air-passage layer including a plurality of air-passage microchannels, a working fluid layer including a plurality of working fluid microchannels, and a sealing layer coupled to the working fluid layer to provide a working/sealing layer set. The working/sealing layer set includes an arrangement of raised pedestals. The raised pedestals may extend from the working fluid layer to the sealing layer and contact the sealing layer.

A heat exchanger is disclosed that includes a cold heat exchange zone including a foam material having an annular geometry and having fluid distribution and collection slots configured to distribute a cooling fluid circumferentially through the foam material.

Disclosed in the present invention are a distributor for a plate heat exchanger, and a plate heat exchanger. The distributor includes; a tube part having a tube wall and having a first end and a second end; a first flange formed at the first end; and a connecting protrusion. The connecting protrusion projects from the tube wall of the tube part in a direction away from an axis of the tube part, and projects from the first flange at the inside of the outer edge of the first flange in a direction towards the second end of the tube part; the connecting protrusion has a connecting protrusion wall, which has an axial connecting protrusion wall that faces in the axial direction of the tube part and is remote from the first flange, the axial connecting protrusion wall being between the first end and the second end of the tube part, and having at least one through-hole. The distributor and plate heat exchanger according to embodiments of the present invention may reduce the manufacturing difficulty, and not only ensure excellent distribution, but may also avoid the risk of the through-hole being blocked by solder during brazing.

Various embodiments include heat exchangers and methods of making heat exchangers from a series of stacked plates each made of two foil sheets bonded together in bonding locations forming fluid flow passages between the foil sheets in regions where the foil sheets are not bonded. An inlet port and an outlet port located at opposite ends of the planar extent of the two foil sheets extend through the foil sheets perpendicular to the planar extent of the foil sheets. The inlet and outlet ports provide access for a first fluid to flow into or out of the internal plate passages formed between the two foil sheets. Interstitial channels are formed between the series of plates and configured to allow the flow of a second fluid between the series of plates, allowing heat to be transferred between the two fluids while isolating the two fluids from one another.

The invention relates to a temperature control device, in particular a cooling device, for an electrical component that is capable of releasing heat during its operation, in particular for an electrical energy storage module. The device has a first outer plate and a second outer plate, as well as a central member arranged between the two outer plates. The central member includes reliefs arranged in order to form, with the outer plates, at least two layers of circulation channels for a heat-transfer fluid. The layers are located on either side of the central member and have the same heat-transfer fluid circulation direction.

A heat exchanger module with a longitudinal axis including a stack of plates defining at least two fluid circuits, at least a portion of the plates each including fluid circulation channels each delimited, at least in part, by a groove. A communication is produced between the channels within a same plate and between all the plates of a same circuit, in a feed or pre-collector zone, with a succession of channel groupings, two-by-two, in the form of bifurcations.

A liquid panel assembly configured to be used with an energy exchanger may include a support frame having one or more fluid circuits and at least one membrane secured to the support frame. Each of the fluid circuits may include an inlet channel connected to an outlet channel through one or more flow passages. A liquid is configured to flow through the fluid circuits and contact interior surfaces of the membrane(s). The fluid circuits are configured to at least partially offset liquid hydrostatic pressure with friction loss of the liquid flowing within the fluid circuits to minimize, eliminate, or otherwise reduce pressure within the liquid panel assembly.

A plate-type heat exchanger includes heat-exchange plates which are mutually stacked and facing each other so as to define, in the space between them, at least two passage channels. The heat-exchange plates have respective entry apertures which are substantially mutually adjacent so as to define an entry conduit. The entry conduit is connected with the passage channel of the corresponding fluid through at least one orifice. The entry apertures have respective collar-like edgings. Each one of the collar-like edgings has an abutment flange which extends radially with respect to the axis of the entry apertures and is adapted to engage, by contact, the abutment flange of the collar-like edging of an adjacent heat-exchange plate.
